The link tales you to the 2012 Marine Corps Exposition. Vendor from LSAT gives a brief on a new design for a machine gun (MG) two variants. It is 1/2 the weight of current in service MG and the AMMO casings are made from polymer! This cut the weight for the ammo by 1/2 also. The say the technoligy can be "scaled" to fit any caliber. Another application: polymer rounds for my polymer mag, for my Glock. Of course all the Die Hard 1911
deciples will hate them. LOL
